They could be unconstitutional. The ability of Congress to delegate its authority to the President does have limits. If companies (the ones in a financial position to do this) sued, they'd have standing and could make their case. Whether it's successful or not would take a while to find out, and this is an instance where judges would likely leave the tariffs in place until the suit was settled in a court (before appeals) if the plaintiffs won.
they could be unconstitutional, but does that matter? the executive gets to enforce whatever it wants however it wants. nobody has to listen to congress or the courts when the executive is all aligned on what theyre gonna do
No, if it were ruled unconstitutional and the President continued to enforce the policies then Congress would be justified in impeaching and removing the President. This is unlikely to actually happen with the current Congress, however.
Could the President remain in office after an impeachment? Ask again in 2-3 years, but today, no. He'd be removed, no federal employee (civilian or military) would continue to take orders from him except perhaps his Cabinet and the DOGE boys. They all swear an oath to the Constitution, not to the man. In 2-3 years, though, could be a different culture.
